IMPRQVEMENT IAN RuFFLERs.

Specification forming part of Letters Patent 1912714, dated November 2.8, 1876; application filed'. A" l June'2f6,1875. f v, v

To all whom it may concern:

Be it known that L'JAMns FRANKLIN KEL- LOGG, ot' Forestville, in the county-ofGhautauqua, in the- State ot' New York, have in'- vented certain new and uset'ul Improvements in Ruftle'rs adapted for use with'sewingma v chines either as a permanent or a temporary temporary attachment; and 'I Ido hereby declare that the following specication',`taken in connection with the drawings furnished,and forming a part of the saine, is a clear, true, and complete description of the same.

My invention consists in the novel combination, with a vibrating rufliing-linger, of a reciprocating sliding bar, an auxiliary lever, and an operatinglever, arranged for operative connection with thev needle-bar ot' a sewing-machine, whereby the rattling-linger is vibrated and made to forcibly engage with the fabric during its forward movement, and also vibrated and made to retreat without compressing the fabric, simultaneously with the movement of the sliding bar.

Figures l and 2 represent, in perspective and in top view, a rufller embodying my invention.

It will be understood that my rufliers'belong to that class which operate upon the upper surface of the fabric to be rui-lied, instead of the lower or under surface'. I

Like all ruftlers ot' this general class, mine is mounted on a bed-plate, as at A, and, when employed as an attachment, it is provided with the usual attaching-slot, as at a. lt has also the projecting arm, ports an upwardly-turned dle-hole, as heretofore.

Gommencing with the operative lever B, it will be seen that it is provided with the usual means for connection ,withthe needle-bar of the sewing-machine. YThis operative lever may be arranged, however, to be driven downward by the needle-bar and forced upward by a spring, or forced downward by a spring and driven upward by the needle-bar, without departing from the main feature of my invention, as will be hereafter more fully described.

It will be seen that the operative lever B is pivoted, as at o, to a vertical standard on the bed-plate.

plate having a nee- Said lever is of the bell-crank oras at b, which sup-v der, and its lower or nearly vvertical arm is composed of two parts,asv at d 'andidh 'Gdenotes a sliding ban-which lis viitted to guidebearings formed in a vertical vextension of the bed-plate.` This sliding'bar has, at its front end and on its rear side,'a guiding-arm, asy at c, which, by *engaging in a'slot -inthe bedplate, (shown in Fig.- -2,)secures the adjacent end'of the sliding barfagainstv undue lateral vibration. The ruffling-iinger D vhas a bearingplate at f, as heretofore constructed, by means of an extension of the bed-plate. This bearing-plate, in operation, is between the main fabric and the strip to vbe ruflied and stitched thereto. rufling-nger is toothed, and at its end is curved slightly downward. The upper surface of the bearing-plate fis, for a short distance, provided with longitudinal scores or grooves corresponding in position with the teeth of the finger. In form, the rufing-nger, as a whole, resembles a bell-crank lever pivoted to the sliding, bar, as at g. One end thereof has a lateral bend and a longitudinal extension, which terminates at the teeth. The other or upper end terminates in a flat semicircular head, as at h. i p It will here be observed that, .if the fiat head h be raised', the toothed lingerwill be depressed and forced to engage with thel'abric, and that if said head be depressed the toothed finger will be raised from the fabric.. E denotes an auxiliary bell cranklever,also pivoted to the sliding bar, as at 't'. Its horizontal arm, at its outer end, is provided with a semicircular jaw, which embraces the head h ofthe ruffling-fingerlever. The opposite or vertical arm ot' this lever E is provided with a laterally-projecting stud, as atvk. It will be seen that this stud k is so placed with relation to the coincident edges of armsv d and d of the operative lever that when said lever is vibrated these arms alternately engage with the stud, and, in doing so, and lower the toothed end ot' the rattling-finger.

With these parts thus constructed, when the operative lever is fully vibratecl by the needle-bar of a sewingmachine; the sliding bar is driven forward and backward practi- The operative end of the` alternately raise cally simultaneously with a downward and upward movement of the toothed end of the ruitlinginger.

When adapted only for making ruffles of one particular degree of fullness, the two arms d d are made non-adjustable with relation to each other; but when adapted for general domestic uses the arm d is separately made, and rendered adjustable by pivoting it independently, as at Z, and combining therewith an adjusting-screw, as at m. y

A graduated scale may be employed near the adjusting-screw, as indicated in the drawing, for properly setting the movable arm of the lever in `each instance.

At F I show agude, which is rendered longitudinally adjustable by means of a slot and a set-screw, as seen in Fig. 2. It is composed of several strips of spring metal, arranged so as to afford several intervening spaces through which the several thicknesses or strips of fabric are conducted toward the stitching mechanism. It is also arranged to compress the fabric at the outer ends of the spaces, thereby securing a desirable degree of tension on `the fabrics, and keeping them straight and smooth without the necessity of constant manipulation by the operative. Having thus described my invention, I claim as new and desire to secure by Letters Patent- `The combination, with the stationary bearing-plate, of' a rocking or vibrating rufingiinger, an auxiliary lever, a sliding bar on which the nger and lever are mounted, and

an `operating -lever arranged to engage with the auxiliary lever, and thereby move the sliding bar and actuate the ruffling-nger, substantially as described, whereby the ruftlingiin ger ismade to compress the fabric between it and the bearing-plate to move the fabric forward on said platefand, in retreating, is lifted from the fabric by the vibration of the operating-lever, as set forth.
